Chapter 4, Problem 4-6(choose chapter or problem)
The crane can be adjusted for any angle \(0^{\circ}\ \leq\ \theta\ \leq\ 90^{\circ}\) and any extension \(0\ \leq\ x\ \leq\ 5\ m\). For a suspended mass of 120 kg, determine the moment developed at A as a function of x and \(\theta\). What values of both x and \(\theta\) develop the maximum possible moment at A? Compute this moment. Neglect the size of the pulley at B.
